As earlier of the modern technology everyone used to buy software’s, data, tools and other required materials for their systems from the market. As by the coming of the torrents like bit torrent the large data is shared globally in servers could easily downloaded with minimum internet band width. As this effected the market from regular buyers from direct market approach.
As due to this type of sharing from peer-to-peer networks have been estimated to collectively account for approximately 43% to 70% of all Internet traffic from place to place. It has large internet traffic where everyone is interested in getting files from it as it costs nothing.
Here in this the server has the file that is needed by the user where as there are many other computers that are connected to the server host. The computer that are connected to the server has download the file according to the user wish (where as after the complication of download you can see seeding) this is because the downloaded file or data is needed by other user, so the middle computer seed the data in the process of seeding and sends the file to the other computer where it acts as peer that is connected to it. Here in this way a large amount of data is shared in the server and could easily obtained or downloaded by the used.
A user who wants to upload a file first creates a small torrent descriptor file that they distribute by conventional means (web, email, etc.). They then make the file itself available through a BitTorrent node acting as a seed. Those with the torrent descriptor file can give it to their own BitTorrent nodes which, acting as peers or leechers, download it by connecting to the seed and/or other peers (see diagram on the right).
The file being distributed is divided into segments called pieces. As each peer receives a new piece of the file it becomes a source (of that piece) for other peers, relieving the original seed from having to send that piece to every computer or user wishing a copy. With BitTorrent, the task of distributing the file is shared by those who want it; it is entirely possible for the seed to send only a single copy of the file itself and eventually distribute to an unlimited number of peers.
The transfer speed is affected by a number of variables, including the type of protocol,the number of seeds and peers that the torrent file has and the amount of traffic on the server and the number of other computers that are downloading the file. If the file is both large and popular, the demands on the server are great, and the download will be slow.
So by the above factors the speed of the torrent depends and thus the large data is transferred to the individual systems.
